This is a pure exercise in style from the Luc Besson school of film making. A handsome gangster joins ranks with a school of dropouts who populate the Parisian subway system, hounded (but never phazed) by transportation police. The trouble is that head honcho Fred has fallen in love with the pretty but stroppy wife of one of his BCBG victims, and strife ensues below the streets of gay Paree.
Christopher Lambert is amazing as the stylish rebel gangster with a heart, Fred; Isabelle Adjani is pretty but, as always, deeply annoying -- she just exudes arrogance from the bottom of her dainty little heart. On the sidelines we see an impossibly young Jean-Hugues Anglade, Jean Reno and Jean-Pierre Bacri. I actually didn't recognise Reno, that's how young and unknown he is here.
If you have a deeper interest in cinema, this is a straight ten. It's amazing how Besson brings together great style, action, fun, pace, acting, dialogue and amazing characters. Unlike most directors who film in the province and try to make it look like Paris, Besson films in Paris but makes it look like Metropolis.
Unfortunately, there isn't much of a plot and zilch suspense. The film starts with a heated heart-to-heart between Fred and pretty Héléna, and since we are aware that their affair can't end but unhappily (albeit in an incredibly chic way), the suspense is exactly zero. So if you just want entertainment, you should better pick one of Besson's later movies.
